ARCH- SHANK FOR SHOE-SOLES.

Specification of Letters Patent.

Patented May 11, mos.

Application filed January 2, 1909. Serial No. 410,551.

To all whom it wit y 601L661"!!! and (-nARLEs E. EATON, citizens of the United States, and residents of Montell'o, Brockton, in the count of Plymouth and State of ltlassachusetts, have invented a new and Im )roved Arch-Shank for Shoe-So es, of which t e following is a full, clear, and exact description. 7 W

-The invention is an improvement in arch su )porting shanks as are-attached to the inside of the outer soles of shoes, and is designed to. replace the customary wood and steel shanks and afiord a strong economical su ort-which is easily and securely applied. 0 this end the invention consists of an arch supporting shank of sheet metal, having tongues staln ed therefrom to secure the shank to the s 0e sole, with the tongues arrangednear the opposite ends of the shank, and the points thereof as stamped out, directed outwardly, and longitudinal ribs pressed in the shank from its under side and I respectively arranged at the opposite sides of the tongues.

Reference is tobe had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. Figure 1 is 'a perspective viewof an outer shoe sole with our improved archsupporting shank applied thereto; Fi ,2 is a side View of a shoe, partly in ion itudmal central section, having our improve arch sulpporting shank;

removed from the sole; and Fi '4 is a cross-section of the shank substantially on the line '4-'4 of Fig. 3.

We construct our improved arch support-'- i'ng shank 5 of sheet metal, preferably of a spring nature, and shaped to conform to the sole 0 the shoe atthe arch but-of substantially less width, thus the side edges of the shank are convex, the heel edge rounding and Y points of the tongue being directed toward the ends at the time of stamping out, and the tongues .afterwardbent downwardly at approximately right angles to the shank, as

shown in Fig. 4. The shank is stiffened and strengthened by pressing therein from the under side, longitudinal ribs 7, which are rel i l i I i spectively arranged at opposite sides of the Be it known that we, TIMOTHY F. EATON tongues and'terrnlnate s ort of the ends of the shank, asshown in Fi 3, whereby'these elillds may be pressed closely to the sole of the s oe.

In applying the shank to an outer shoe sole 8, openings or slots are formed in the sole a distance apart e ual to the distance between the tongues of t e shank and at points to properly locate the shank on the arch. The

tongues are passed through these slots from the upper face of the sole, and the points of the ton ues clenched by bending them toward each ot or into engagement with the under side-of the sole, as shown inFig. 2, thus se-- curely connecting the shank and sole-togethen'. This manner of unitin these parts dispenseswith the use of suc devices as screws, nails, etc., and avoids possible chance of the plate working loose. Any strain tending to shift the shank forwardly "or. rearwardlywill be efiectually resisted by the rear and forward tongues respectively.

The shank may be arched at the time of arching the sole and will occupy the positionin the finished shoe as shown in Fi 2, the ribs 7 not only serving to strengt on and stiifen the shank but also engaging in the lea'theror other material above andpreventin the shank froin working sidewise.

'aving thu'sjdesc'ribed our invention, we claim as newjand: desire to secure by'Letters Patentz' r The combination of an outer shoe sole, an arch shank of sheet-material having tongues stamped therefrom, with the oints of the tongues as stamped out, respectwelydirected toward the o posits-ends of the shank, and ribs pressed ongitudinally. into the shank from the under face thereof and arranged at opposite sides of the tongues, said tongues being bent downwardly and passed through the outer shoe sole, "and bent inwardly toward each other a ainst the bottom of the sole to secure the s ank to the upper face of the sole. g

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
